nanobanana prompt: Levitating Obsidian Product with Spectral Iridescence

March 27, 2026
This prompt creates a hyper-realistic visualization of a product isolated in 3D space against a pure black background. The artistic breakdown reveals a levitating object with ultra-glossy obsidian glass material that exhibits brilliant spectral iridescence and internal volumetric lighting. The scene features crisp ray-traced reflections, high-index caustic refraction, and intense holographic highlights in electric blues and magentas, achieving a futuristic aesthetic through precise technical constraints that eliminate all supporting elements. #ProductVisualization #HyperRealism #CGIArt #MaterialDesign
